We addressed the question of bottom-up versus top-down control of marine ecosystem trophic interactions by using annual fish catch data and satellite-derived (SeaWiFS) chlorophyll a measurements for the continental margin of western North America. Findings reveal a marked alongshore variation in retained primary production that is highly correlated with the alongshore variation in resident fish yield. The highest productivity occurs off the coasts of Washington and southern British Columbia… Expand
The ups and downs of trophic control in continental shelf ecosystems.
TLDR
The data suggest that ecosystem susceptibility to top-down control and their resiliency to exploitation are related to species richness and oceanic temperature conditions, which could produce ecosystem guidelines to regulate and manage fisheries in a sustainable fashion. Expand
Strong Top-Down Control in Southern California Kelp Forest Ecosystems
TLDR
A multiyear, large-scale data set of species abundances for 46 species in kelp forests from the California Channel Islands with satellite-derived primary production found top-down control explains 7- to 10-fold more of the variance in abundance of bottom and mid-trophic levels than does bottom-up control. Expand
Shifts in North Sea forage fish productivity and potential fisheries yield
TLDR
The results demonstrate that fisheries reference points for short-lived planktivorous species are highly dynamic and respond rapidly to changes in system productivity, indicating that ecosystem resilience may decline with productivity. Expand
Reconciling differences in trophic control in mid-latitude marine ecosystems.
TLDR
A combination of compensatory population dynamics and accelerated demographic rates in southern areas seems to account for the greater stability of the predator species complex in this region, mirroring the shifting pattern of trophic control. Expand
How zooplankton communities are shaped in a complex and dynamic coastal system with strong tidal influence
Abstract Temperate coastal marine environments are typified by strong seasonality and highly productive annual spring phytoplankton blooms. However, in areas of strong tidal activity, coastal watersExpand
Understanding What Drives Food Web Structure in Marine Pelagic Ecosystems
Coastal ecosystems constitute <3% of the world ocean area yet contributes to >80% to world fisheries catch. Understanding food web structure is essential in ecosystem-based management, predictingExpand
Impacts of climate change on regional primary and fisheries productivity in an Australian upwelling system
Coastal upwelling regions account for 20% of global ocean productivity. These extremely productive wind-driven ecosystems are vulnerable to climate change. Here, I investigate relationships betweenExpand
Phytoplankton bloom dynamics and development of methods for estimating primary productivity in the California Current System
The California Current System (CCS) is a coastal upwelling region that supports diverse and abundant mesopredators including fishes, seabirds, and marine mammals. Many fisheries, including PacificExpand
Upwelling-like bottom intrusion enhances the pelagic–benthic coupling by a fish predator in a coastal food web
Upwelling regions where nutrients are transported from deep to surface waters are among the most productive in the oceans. Although it is well known that the upwelling affects fishery productionExpand
Multi-level trophic cascades in a heavily exploited open marine ecosystem
TLDR
This work shows for the first time a four-level community-wide trophic cascade in the open Baltic Sea, and suggests that in order to dampen the occasionally harmful algal blooms of the Baltic, effort should be addressed not only to control anthropogenic nutrient inputs but also to preserve structure and functioning of higher Trophic levels.

Climate Impact on Plankton Ecosystems in the Northeast Atlantic
TLDR
Future warming is likely to alter the spatial distribution of primary and secondary pelagic production, affecting ecosystem services and placing additional stress on already-depleted fish and mammal populations. Expand
Control of marine fish production
TLDR
Fish production was more sensitive to variations in phytoplankton production in oligotrophic than in eutrophic marine environments as a result of a nonlinear decrease in f, the ratio of new to total production, as primary production decreased. Expand

TLDR
An expansion of a classical minimal Daphnia-algae model is presented to account for effects of fish as a top predator and shows how intrinsic predator-prey oscillations in the planktonic system can facilitate the switch to the algal-dominated regime where Daphia is controlled by fish. Expand
